It is now known that venting crawl spaces is a bad idea. Vented crawl spaces let in outside air that can increase heating bills in the winter and cooling bills in the summer, and actually lets more moisture into our homes.

By encapsulating the crawl space with our VaporLocĀ® system, we can close your crawl space vents for good. Along with the VaporLoc EliteĀ® encapsulation system, TerraFirma vent covers provide a clean and easy way to save money on your energy bills all while keeping excess moisture out of your crawl space to create a healthier environment for your family.

Crawl Space Vent Cover Benefits

Creates a Healthy Space When moist air enters a vented crawl space, the air will condense on cooler crawl space surfaces, ruining insulation and encouraging mold and mildew, and opening your home to insects and other unwanted pests. Crawl Space vent covers keep your crawl space dry, mold, rot and pest free.

Energy Efficient Energy Efficient Crawl space vent covers play an important role in sealed crawl spaces by closing out the air movement that would otherwise occur through vent openings. Sealing your crawl space with vent covers saves you money by blocking that air movement that is known to increase energy bills.

Durable Materials Crawl space vent covers by TerraFirma are made out of "worry-free" materials that are made from durable plastic that you will never to have to worry about painting or replacing. They are quickly and easily installed over your existing vents.
